Pediatric kidney disease has a lower prevalence than other pediatric conditions and has a notably different etiology from kidney diseases occurring in adults. Furthermore, the pediatric population is unique in that they experience ongoing growth and development, distinguishing them from adult patients. Consequently, pediatric patients with kidney disease require a more specialized and meticulous nutritional management plan compared with adult patients. To address this need and promote optimal dietary practices for pediatric patients with kidney disease, pediatric nephrologists from the Korean Society of Pediatric Nephrology and nutritionists from the Korean Society of Clinical Nutrition have collaborated to formulate nutritional guidelines specifically tailored to Korean dietary patterns. These guidelines offer detailed, nutrient-specific recommendations regarding the consumption of energy, protein, calcium, phosphorus, and potassium while providing practical, culturally relevant guidance intended to support both pediatric patients and their caregivers.
